processing of bauxite into alumina

  • Bauxite The Aluminum Association

    Bauxite is primarily comprised of aluminum oxide compounds (alumina) silica iron oxides and titanium dioxide. Approximately 70 percent of the world s bauxite production is refined through the Bayer chemical process into alumina. Alumina is then refined into pure aluminum metal through the Hall–Héroult electrolytic process. Mining bauxite
